- The activity of lysosomal enzymes, such as beta-hexosaminidase (Hex), is increased in the plasma and serum of diabetic patients. A positive association has been shown between enzyme activity and glycated proteins, indicating an association with the degree of metabolic control. Several isoenzymes of Hex exist. Studies have reported different proportions of the isoenzymes in plasma from diabetic patients, compared with healthy subjects. In the present study, Hex isoenzymes were examined in 76 Type 1 diabetic patients, of mean age 37.4 years (SD 12.9) compared with 38 age- and sex-matched healthy control subjects in an attempt to evaluate the influence of long- and short-term changes in blood glucose levels on these isoenzymes. The results show that Hex A activity (p<0.01), but not Hex B activity, was higher in the diabetic patients. Hex A activity was positively associated with both the actual blood glucose levels (r = 0.48, p<0.001) and haemoglobin A1c (HbA1c) (r = 0.43, p<0.001), while Hex B activity was associated with the level of HbA1c only (r = 0.42, p<0.001). Both Hex A and B activities were also positively associated with early signs of diabetic nephropathy (e.g. urinary excretion of Hex, fractional albumin excretion ratio and urinary albumin). There was no association between Hex A and B activities and different degrees of retinopathy. In conclusion, the present study demonstrates an association between Hex A and B and metabolic parameters in diabetes as well as with clinical signs of early diabetic nephropathy, but no association with the degree of retinopathy. Furthermore, Hex A seems to be more influenced than Hex B by short-term changes in blood glucose levels.
